Solve x^3 = 1 over 8.<br><br> 1 over 2<br> ±1 over 2<br> 1 over 4<br> ±1 over 4
Oduvanchick [21]

Answer:

x = 1/2

Step-by-step explanation:

x^3 = 1/8

Take the cube root of each side

x^3 ^ (1/3) = (1/8)^ (1/3)

Rewriting 8 as 2^3

x^3 ^ (1/3) = (1/2^3)^ (1/3)

x = 1/2

What is the sum of the first 7 terms of the geometric series:
Fiesta28 [93]

Answer:

-15.875

Step-by-step explanation:

First, we can sum up the first 5 terms.

-8 + (-4) = -12

-12 + (-2) = -14

-14 + (-1) = -15

-15 + (-1/2) = -15.5

Next, we can find a pattern in the data. We can tell that the next number is one half of the current number. For example, -4 is one half of -8. To find the next number, we simply multiply our current number by one half. Thus, the sixth number is -1/4 and the seventh is -1/8. Adding these to our current total, we have

-15.5 - 1/4 = -15.75

-15.5 - 1/8 = -15.875 as our answer

ArbitrLikvidat [17]

Answer:

\frac{1}{6}

Explanation:

Since there are 6 possible outcomes that number is the denominator. out of the six there is only one 5 on a standard number cube. So, there is a \frac{1}{6} possibility of rolling a 5. This fraction can't simplify so that is the answer.
